1 When you use rigid tapping mode M code

command (No.5200#0=0), the system refers to

No.5210 or No.5212 as the value of M code.

Therefore, please set No.5210 or No.5212 to

suitable value before machining.

TOOL COND.

Data item

Meaning

TOOL DIAMETER

Face mill diameter

NOTE

1 Tab ‘TOOL COND.’ is enabled when bit 0 (TLG) of

parameter No. 27002 = 1.

2 The operator ordinarily sets the above data on the

tab of ‘TOOL DATA’ in Tool Offset window.

Therefore, it is not necessary to display the tab

‘TOOL COND.’

CUT COND.

Data item

Meaning

THICKNESS

Face mill diameter

FINISH AMOUNT

Finishing allowance in facing

CUT DEPTH OF RADIUS

Depth of cut in the tool radius direction to the next

cutting path

CUT DEPTH OF AXIS

Depth of cut in the tool axis direction per cutting

operation

FEED RATE - RADIUS

Feedrate applicable when cutting is performed in

the tool radius direction

FEED RATE - AXIS

Feedrate applicable when cutting is performed in

the tool axis direction

NOTE

If the parameter 27030#1=1, only the menu of

perpendicular directions to “CUTTING

DIRECTION” can have been displayed during in

case of selecting “CUT SHIFT DIRECTION”. Thus,

the extra selection can be removed.

DETAIL

Data item

Meaning

INITIAL FEED OVERRIDE

Feedrate override value for the first cutting. The

initial value is 100 (1 to 200, positive value).

CUTTING METHOD

[SINGLE] : Cutting in the tool radius direction is

always performed in the same

direction.

[ZIGZAG] : Cutting in the tool radius direction is

performed back and forth.

(COPY)

PATH MOVE METHOD

[PULL]

: Retracts to point R before moving to the

start point of the next cutting path (in

the tool axis direction).

[KEEP]

: Moves to the start point of the next

cutting path directly without retracting to

point R.

Remark1) This data item is indicated only when

[ZIGZAG] is selected for CUTTING

METHOD.

Remark2) This data item is enabled when the

parameter No.27030#0(FC0) = 0.

Remark3) In case that the movement is done

by 1 axis, tool is kept even if [PULL]

is specified.

Remark4) If [KEEP] is specified, an end point

of previous cutting motion is

adjusted in order to enable a tool to

move with 1 axis to next cutting

start point

(COPY)

PATH MOVE FEED RATE

Feedrate applicable when the tool moves to the

start point of the next cutting path. In case that

the feedrate is set to 0, the tool moves at a

rapid traverse rate.

Remark1) This data item is indicated only when

[ZIGZAG] is selected for CUTTING

METHOD.

Remark2) This data item is enabled when the

parameter No.27030#0(FC0) = 0.

(COPY)

CLEARANCE OF AXIS

Distance between the surface of a blank being

machined and a cutting start point (point R) in the

tool axis direction (radius value)

Remark) By referring to the parameter No.27009

(minimum clamp value), the system sets

the data as Initial value.

CLERANCE OF RADIUS

Distance between the end of a blank being

machined and the end of the tool placed at the

retract position (radius value)

Remark) By referring to the parameter No.27009

(minimum clamp value), the system sets

the data as Initial value.
